[PATCH 0/2] spi: imx: don't loop endlessly

[Uwe Kleine-König]

Hello,

during bringup of an i.MX7 board I am faced with cspi_2_3_xchg_single not
returning. I don't know yet why this happens, but with this patch set it at least
doesn't block barebox.

I didn't test on a working board, maybe the timeout (10 µs) I chose is too tight?

Best regards
Uwe
